1. A three-dimensional (3D) depth sensor comprising:
- a plurality of light sources configured to irradiate light to an object, the light having different center wavelengths;
an optical shutter configured to allow reflected light reflected from the object to pass through; and
an image sensor configured to filter the reflected light having passed through the optical shutter and detect the filtered light,wherein the plurality of light sources are configured to control intensity and a center wavelength of the light irradiated therefrom based on a magnitude of a driving voltage.
